Interactive visualizations, guided problem sets, and step-by-step convergence analysis for students learning numerical methods. Canvas LTI 1.3 with automatic grade passback.
Method
Equation f(x)
Initial Guess x₀
Convergence
Initialize: x₀ = 1.000000
f(x₀) = −1.0000e+0, f′(x₀) = 2.0000e+0
Iter 1: x₁ = 1.50000000
Error: |x₁ − x₀| = 5.0000e−1
Iter 2: x₂ = 1.41666667
Error: |x₂ − x₁| = 8.3333e−2
Iter 3: x₃ = 1.41421356
Error: |x₃ − x₂| = 2.4510e−3
Iter 4: x₄ = 1.41421356
Error: |x₄ − x₃| = 1.5943e−12
✓ Converged in 4 iterations
Root ≈ 1.41421356 (√2 exact)
Quadratic convergence: notice digits doubling each step

Built for institutional use. We collect only what's needed and protect it at every layer.
All traffic over HTTPS/TLS. Canvas JWTs verified server-side via JWKS on every launch — tokens never touch the client.
Supabase PostgreSQL with RLS policies enforced at the database layer. Students can only read their own submissions.
We store name, institutional email, and course enrollment. No Social Security numbers, grades beyond NumericaLTI, or payment details.
OIDC-based launch flow with state and nonce validation. Replay attacks blocked by one-time cookie verification.
